About

The purpose of this study is to assess progression-free survival (PFS) from treatment with ibrutinib plus venetoclax (I+VEN) compared with obinutuzumab plus chlorambucil (G-Clb) as assessed by an Independent Review Committee (IRC).

211 participants in 2 patient groups

Treatment Arm A: Ibrutinib and Venetoclax (I+VEN)
Experimental group
Description:
Participants will initially receive ibrutinib (420 mg \[milligrams\]/day) for 3 cycles. Venetoclax dose ramp up (from 20 to 400 mg over 5 weeks) will begin at Cycle 4 and the combination of ibrutinib and venetoclax will be given for 12 cycles (each cycle is equivalent to 28 days). Participants who subsequently develop progressive disease may enter to Subsequent Therapy Phase to receive single-agent ibrutinib until disease progression or unacceptable toxicity.
Treatment:
Drug: Ibrutinib
Drug: Ibrutinib (as Subsequent Therapy)
Drug: Venetoclax
Treatment Arm B: Chlorambucil and Obinutuzumab (G-Clb)
Active Comparator group
Description:
Participants will receive chlorambucil and obinutuzumab (G-Clb) for 6 cycles. Participants will receive obinutuzumab, 1000 mg intravenously (IV) on Days 1, 8 and 15 of Cycle 1, and on Day 1 of Cycles 2 to 6 and chlorambucil 0.5 milligrams per kilogram (mg/kg) body weight, on Days 1 and 15 of Cycles 1 to 6. Participants who subsequently develop progressive disease may enter to Subsequent Therapy Phase to receive single-agent ibrutinib until disease progression or unacceptable toxicity.
Treatment:
Drug: Ibrutinib (as Subsequent Therapy)
Drug: Chlorambucil
Drug: Obinutuzumab
